Hashim had some money. His sister had $75.10. After Hashim gave his mother $28, he had $15.20 less than his sister. How much did he have at first?

$87.90

Step-by-step explanation:

Let the amount of money Hashim had be $Y. As such, if he gives his mother $28, he would have $Y - $28 left.

If he had $15.20 less than his sister and his sister had $75.10, then we can say that what he had left  $Y - $28 is equivalent to the difference between $75.10 and $15.20.

This is

$Y - $28 = $75.10 - $15.20

Y = $28 + $75.10 - $15.20

= $87.90

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
